Definitions

  • the signaling material only plays its role imperfectly, and the operator of the shovel may not see the signaling material, and thus not be alerted to the presence of an underlying pipe. .
  • the invention makes up for. Its subject is a signaling material of the aforementioned type, and in which the signaling element consists of at least one straight, but discontinuous strip, made of a material having good resistance to breakage, and associated with a support. having a low breaking strength.
  • the support can finally be biodegradable.
  • the support consists of a plastic mesh on which are fixed two ribbons of plastic delimiting two gussets which serve as housing for the elements of discontinuous bands mounted freely in these gussets, the ends of each element of band being shifted from band to band.
  • the support consists of a simple strip of plastic material with low breaking strength on which are fixed, in line with one another, the independent elements of a strip of plastic material with high resistance at the breakup.
  • the signaling material is made, in combination, by several strips of plastic material which, having a high breaking strength, are discontinuous, are offset at least two by two, and are connected by transverse elements to low breaking strength.
  • the material intended for signaling an underground pipe consists of a plastic mesh (1) carrying two plastics tapes (3) which are welded longitudinally along their two edges and thus delimit, with the wire mesh, two gussets designated by (4).
  • Each of these two gussets serves as a housing for a reinforcing element associated with the mesh.
  • This reinforcing element is actually constituted by a plurality of individual elements placed end to end and freely inside the gussets (4).
  • These elements each consist of a strip (5) made of a plastic material having a breaking strength much greater than that of the mesh (1) and that of the two strips of plastic material (3) attached to the mesh. It is essential to observe that the bands or elements (5) placed in one gusset (4) are offset from those placed in the other gusset.
  • the signaling material of an underground pipe consists of a simple strip (6) made, for example, of plastic material and having a low resistance to breakage, tape on which are fixed, one after the other, individual strips (7) made for example also of plastic but having a high resistance to breakage.
  • the signaling material has a general form of ladder. It is made up of four series of plastic bands with high breaking strength. These bands are designated respectively by (8), (9), (10) and (11); they are parallel and are connected by wires or similar elements (12) made of a plastic material with low breaking strength. These wires or other elements (12) serve as spacers for the main elements (8, 9, 10 and 11) and ensure the cohesion of the assembly. It is important to note that all the middle bands are offset from each other.
  • the discontinuous elements or bands, respectively are made of a material with higher breaking strength than the support to which these elements are associated, and provided that in the case of the forms of execution of FIGS. 1, 2 and 4, the ends of the discontinuous elements are offset from one strip relative to the other.
  • the signaling material perfectly fulfills its role in all cases, including when carrying out a search or a trench with a mechanical shovel.
  • the bucket of the shovel takes the earth from the trench, it exerts on the signaling material enough traction to cause the breaking of the mesh (1) (in the case of Figures 1 and 2), of the tape (6) (in the case of Figure 3), and spacers (12) (in the case of Figure 4); but the bands (5) ( Figures 1 and 2), (7) ( Figure 3), and (8, 9, 10 and 11) ( Figure 4) are not affected by this break, not only because they are made of a material with high resistance to rupture, but also and above all because they are constituted by a plurality of independent elements placed end to end.
